Frequent reordering is not useful because of user habits. Data should be read carefully instead of a blind decision. 'Too many people click on Jobs, then let's carry it on top' approach cannot always a good thing. It depends on what you are trying to achieve.
For example, imagine that your website's primary focus is messaging, message button isn't clicked too much. People love learning section of your application, and it's clicking rate is much higher than the message. What will you do? Data says learning section is important, but your company wants to sail with the messaging feature. You probably heard the Henry Foard saying: 'If I had asked people what they wanted, they would have said faster horses.'
So don't make rash decisions, investigate data carefully.
